The purpose of this standard is to establish a normative definition of communication between patient-connected ventilator devices and other medical devices and information systems in a manner that enables plug-and-play and semantic interoperability.The scope of this standard is medical device communication for patient-connected ventilator devices. It constrains the general IEEE 11073 terminology and information model standards (IEEE 11073-10101 and 11073-10201, respectively) to specialize their application to ventilator devices. Guidance is also provided for the use of IEEE 11073 Application Profile standards (IEEE 11073-20xxx) and Transport Profile standards (IEEE 11073-30xxx) for ventilator connectivity.
